Abstract: An adhesive is provided that has superior bonding strength and that can be beneficially used as a structural adhesive and, when formed into a sheet shape, has superior shape retention. The adhesive includes an acrylic polymer; an epoxy resin in an amount of 80 to 300 parts by mass per 100 parts by mass of the acrylic polymer; at least one type of thermoplastic resin selected from the group consisting of a phenoxy resin and a polyvinyl butyral resin, in an amount of 15 parts by mass or greater per 100 parts by mass of the acrylic polymer; and an epoxy resin curing agent. In such an adhesive, the acrylic polymer is a polymer of monomer components including a (meth)acrylic acid ester having a homopolymer Tg of 80° C. or higher, a nitrogen-containing monomer, and a crosslinking monomer having an epoxy group.

Abstract: A structural adhesive film is provided whereby both adhesion and edge coverage can be achieved. The structural adhesive film (1) includes a first curable resin layer (1a) containing a first thermosetting resin and a first foaming agent; and a second curable resin layer (1b) containing a second thermosetting resin. A curing temperature of the first curable resin layer (1a) is lower than a curing temperature of the second curable resin layer (1b); and a foaming starting temperature of the first foaming agent is lower than the curing temperature of the first curable resin layer (1a).

Abstract: A thermal insulating material which can be efficiently produced while the content of organic matters, such as organic fibers and/or an organic binder, is reduced to the same or lower degree as compared with the thermal insulating material used in a conventional pollution control device (e.g., catalytic converter), and which can be applied to a pollution control element (e.g., catalytic element) while avoiding, as much as possible, an unpleasant feeling to the operator. A thermal insulating material comprising a thermal insulating material body formed of a bulk material of inorganic fibers, and a coating provided on at least one surface of said thermal insulating material body.
